The following example (from the spec) seems quite fragile:
<message>
<body>This XEP supports many things:
* inline markup
* code blocks
* lists
* and possibly more!</body>
<markup xmlns="urn:xmpp:markup:0">
<list start="31" end="89" ordered="false">
<li start="31"/>
<li start="47"/>
<li start="61"/>
<li start="69"/>
</list>
</markup>
</message>
